plus quam dimidio (postice quam antice tertia parte) latiori 

 sparsim obsolete punctulato et foveis paucis impresso, antice 

 sat fortiter (postice leviter) emarginato, hexagonali, lateribus 

 minus late explanatis mox ante basin sinuatis, marginibus 

 validis crassis, angulis posticis subrectis ; elytris fere ut A. 

 Lindensis sed interstitiis alternis postice vix subcarinatis ; 

 antennis ut A. Lindensis. [Long. 6^-, lat. 2~ lines. 



Remarkably like the preceding in respect of its elytral sculpture, 

 but inter alia differing from it (and from all other Adelia known 

 to me) by the singular shape of its prothorax, each side of which 

 is formed by two nearly straight lines meeting in a scarcely 

 rounded angle at a point scarcely behind the middle. The pro- 

 thorax is much less transverse than in A. Lindense, much less 

 explanate laterally, and more narrowed in front. This species also 

 bears a certain resemblance to A. cisteloides, Er., from which it is at 

 once separated inter alia by the strongly thickened lateral margins 

 of its prothorax. As in A. Lindense the seriate fovea? on the 

 elytra are much larger in some examples than in others.

Adelium ^equale, sp.nov. 



Sat nitidum ; sat convexum ; totum nigrum ; capite subruguloso 

 antice sparsim subtiliter (postice magis fortiter) punctulato ; 

 prothorace quam longiori fere partibus tribus (postice quam 

 antice minime) latiori, leviter sat 6rebre punctulato et 

 puncturis magnis paucis (circiter 6) instructo, antice bisinu- 

 ato, postice leviter late emarginato, lateribus sat rotundatis 

 modice explanatis, marginibus sat subtilibus, angulis posticis 

 obtusis ; elytris ovalibus haud striatis, seriatim punctulatis, 

 puncturis in seriebus magnitudine variis latera apicemque 

 versus fere obsoletis, interstitiis perspicue sat crebre punctu- 

 latis ; antennis sat tiliformibus, articulo 3° quam 4 US 5 US que 

 conjuncti vix longiori. [Long. 65, lat. 2\ lines. 



Resembles the preceding two species, A. cisteloides, Er., and 

 some others, in having the longitudinal puncturation of the elytra 

 unequal. In the unique example before me the rows consist of deep
